Antacid is basic, not acidic.
It has a pH of about 6, which makes it an acid. It is meant to dilute stomach acid, but not neutralize it.
Antacid is the opposite of acid. It's a base.
Antacid medication is alkaline, which is also called base. It makes the stomach acid slightly less acidic so that the stomach acid has a pH between 3 and 4.
Makes them harder to compress into tablets (and stay as tablets), and does nothing to neutralize acid.
The prefix for acid is "acid-" and the suffix is "-ic."

The antacid is neutralized, but not as neutralized as it would be if it was in one's stomach. The stomach acid neutralizes the antacid more than the water, because the stomach acid has a lower pH and therefore causes a more vigorous acid-base reaction. It is a chemical change.
